UM1650 UM1750 350mA, Micropower, Very Low Dropout Linear Regulator UM1650S-xx SOT23-3 UM1750S-xx SOT23-5 UM1750Y-xx SOT89-5 UM1750DA-xx DFN6 2.0×2.0 General Description The UM1650/UM1750 series are very low dropout linear regulators designed for low power portable applications. Typical output noise is only 195μVRMS and maximum dropout is just 110mV(Typ) at the load current of 150mA.The internal P-channel MOSFET pass transistor requires no base current, allowing the device to draw only 190μA during normal operation at the maximum load current of 350mA.With a shutdown control pin, the UM1750 consumes less than 1μA current in shutdown mode. Other features include high output voltage accuracy, excellent transient response, under voltage lockout, stability with ultralow ESR ceramic capacitors as small as 1μF, short-circuit and thermal overload protection and output current limiting. The UM1650 series are available in a low profile SOT23-3 package. The UM1750 series are available in low profile SOT23-5, SOT89-5 and DFN6 2.0×2.0 packages.

Note 2: The maximum allowable power dissipation of any TA (ambient temperature) is PD(max)= (TJ(max)–TA)/θJA. Exceeding the maximum allowable power dissipation will result in excessive die temperature, and the regulator will go into thermal shutdown. Note 3: The UM1650/UM1750 is tested and specified under pulse load conditions such that TJ≈TA. Specifications over the -40°C to 125°C operating junction temperature range are assured by design, characterization and correlation with statistical process controls. Note 4: This IC includes overtemperature protection that is intended to protect the device during momentary overload conditions. Junction temperature will exceed 125°C when overtemperature protection is active. Continuous operation above the specified maximum operating junction temperature may impair device reliability. ________________________________________________________________________ http://www.union-ic.com Rev.04 Sep.2017 9/18 UM1650 UM1750 Electrical Characteristics ____________ VSHDN=VIN=VOUT+1V, CIN=COUT=1.0μF, TA=25°C, unless noted.

The output voltage is calculated using: R1 ⎞ ⎛ VOUT = VFB ⎜1 + ⎟ ⎝ R2 ⎠ Where: VFB=1.00V (Typ) (the internal reference voltage) Resistors R1 and R2 should be chosen for approximately 3-5μA divider current. Lower value resistors can be used but offer no inherent advantage and waste more power. Higher values should be avoided, as leakage currents at FB increase the output voltage error. The recommended design procedure is to choose R2=200kΩ to set the divider current at 5μA and then calculate R1 using: ⎞ ⎛V R1 = ⎜⎜ OUT − 1⎟⎟ × R 2 ⎠ ⎝ VFB Where: VFB=1.00V (Typ). ________________________________________________________________________ http://www.union-ic.com Rev.04 Sep.2017 11/18 UM1650 UM1750 Typical Performance Characteristics (Shown for 3.3V Output Option) Quiescent Current vs. Input Voltage IOUT=0mA GND Current vs. Output Current VIN=4.3V Output Voltage vs. Output Current VIN=4.3V Quiescent Current vs. Temperature VIN=4.3V, IOUT=0mA Output Voltage vs. Input Voltage IOUT=350mA Output Voltage vs. Temperature VIN=4.3V, IOUT=10mA ________________________________________________________________________ http://www.union-ic.com Rev.04 Sep.2017 12/18 UM1650 UM1750 Typical Performance Characteristics (Continued) (Shown for 3.3V Output Option) PSRR vs. Frequency Dropout Voltage vs. Output Current IOUT=10mA IOUT=100mA Load Transient Response Noise UM1750S-33, VIN=4.3V, IOUT=20mA to 200mA UM1750S-33, VIN=4.3V, IOUT=150mA, CIN=COUT=1μF 195μVRMS IOUT 100mA/div 500μV/div VOUT 100mV/div 20ms/div 100μs/div f=10Hz to 100kHz Line Transient Response Startup Waveform UM1750S-33, VIN=4.3V, RL=33Ω UM1750S-33, VIN=4.3V to 5.3V, IOUT=100mA VIN VEN 1V/div 2V/div VOUT VOUT 100mV/div 1V/div 100μs/div 10μs/div ________________________________________________________________________ http://www.union-ic.com Rev.04 Sep.2017 13/18 UM1650 UM1750 Package Information UM1650S-xx: SOT23-3 Outline Drawing DIMENSIONS Symbol A A1 A2 b c D E E1 e e1 L θ MILLIMETERS Min Typ Max 1.013 1.15 1.40 0.00 0.05 0.10 1.00 1.10 1.30 0.30 0.50 0.10 0.15 0.20 2.82 3.10 1.50 1.60 1.70 2.60 2.80 3.00 0.95REF 1.90REF 0.30 0.60 0° 8° INCHES Min Typ Max 0.040 0.045 0.055 0.000 0.002 0.004 0.039 0.043 0.051 0.012 0.020 0.004 0.006 0.008 0.111 0.122 0.059 0.063 0.067 0.102 0.110 0.118 0.037REF 0.075REF 0.012 0.024 0° 8° 1.20 2.35 Land Pattern NOTES: 1.
